What our clients have to say

Mr. Hemeier was able to perfectly prepare our team of experts for this complex topic in an in-house training course lasting several days at the highest professional and technical level and at the same time in a pleasant and relaxed atmosphere. He is one of the leading experts in this field who can offer training of this quality, and we give him a clear recommendation!
Tobias Torkler, Senior Software Architect, CompuGroup Medical Software GmbH
Mr Hemeier is a highly valued lecturer whom we are very happy to use. He convinced us with his professional competence and his practical and descriptive way of lecturing. There is always the possibility to ask questions, which are answered to our complete satisfaction. Due to the individual design of the contents, the participants have a great added value which they can directly put into practice. We are happy to recommend Mr. Hemeier!
Stephanie H., Sales Training Centre, Bechtle GmbH
We received training from Mr. Hemeier on our premises with 10 colleagues over a period of several days. Although the subject was not the easiest and there were many topic blocks, it was never boring, and all questions were answered professionally by the trainer. We have gained a lot of competence through this training and can use the newly acquired knowledge well in our company. We recommend the CloudPirates training 100%!
Fred Staudenmaier, IT Infrastructure Architect, AIC Group GmbH
For our in-house training in the area of Kubernetes, we found Dennis Hemeier to be a first-class trainer. His broad and in-depth practical knowledge made the training dynamic and vivid and created a relaxed atmosphere. The structure of the training was also oriented towards our pre-defined requirements, so that we were able to get the best possible benefit from the training. We can therefore recommend Dennis Hemeier with the best conscience.
Roman Asendorf, IT Consultant / IT Administrator, neusta infrastructure services GmbH
Dennis Hemeier from CloudPirates was an excellent lecturer in his Docker & Kubernetes training, and thus brought us a good deal further and closer to these exciting technologies. Due to the modular offer, the training could already be well adapted to our focus beforehand, and Dennis also adapted well to our needs spontaneously during the training. Because the Cloudpirates offers both training and consulting, we had the opportunity to discuss our current challenges after the training, which we gladly took advantage of in the form of a follow-up "ask me anything".

Requirements

For participating in our training sessions

Our training sessions are generally tailored to your prior knowledge and coordinated with you personally. Thus, our training is suitable for both container beginners and experienced users looking to expand their knowledge. Individual parts can be condensed or expanded to ensure you get the maximum benefit from the training.

Ideally, you should have some prior knowledge in Linux administration and be able to use the command line productively. Basic knowledge in Docker/containers and virtualization is also helpful but not required.

During the training, participants work on their own devices, setting up a local Kubernetes cluster or using a learning environment provided by us.

For using your own devices, it's necessary that they support kernel virtualization to run Docker Desktop or Podman. This is generally possible on most recent devices with Linux, macOS, or Windows operating systems. We are also happy to assist with any questions regarding the requirements and setup of your systems.
